annotation Argument against Mr Walkers law — The intellect & instinct in a cross-breed comes from ￭both￭ parents, as￭ in￭ shepherd dogs &c &c — no￭w ￭ one would have thought if one parent gave one part & one another, nothing would be so little divisible as the thinking faculty —

annotation(1) the propagation of plants. as we see in their crossing &c &c. is closely similar to that animals, now, in plants we cannot ‹tra› separate the organs into any two analogous divisions — ‹even if› In plants, accordng to Mr K. either father or mother can give “excitability” (& I daresay other similar cas￭e could be gathered) now excitability or constitutional peculiarities would scarcely be given in ￭one system of [corrected from `or'] organs.—

annotation2d. The kind of argument in favour of it, are such as Phrenologists advance. «(one series affecting muscle & another their supports, ie only in the face)» — does not hold good in my experience. or rather a double answer might be given /

annotationWhen different varieties cross, the offsprng take ‹after› the locomotive system frm th male, because, the male has greatest desire frm the female being very [over] different — according to this «the» law, would be quite interfered with in ‹th› a case where the ‹female› «ova» were impregnated by the semen of the male ,as in fishes & frogs, & yet we know that mule fishes occur ,& that it is not necessary in insects or fish that male should see female.— Moreover, how in cross of black & white man. & different varieties of dogs come there to be litters ‹tak› of puppies some taking after mother & some father. — Again ,there seems to be as much law (& as doubtful) in crosses of plants, the greater desire of the male is absurd — Again in some cases, the cross-bred offsprng vary much. (as in passion flowers described by Sabine) here then no certain law appears to prevail. Again Mr. W. admits the offsprng of cross breeds. p. 220 revert , & explains it by. one having the system of [over] one parent, & another a different one — yet by his “law of crossing” all will have locomotive system of male, & hence the possibility of this Heterogeneity depends on ‹fem› male being less vigorous than female.— (& this is next thing to assumption . for if other wise would have been recognized in human race)

annotation/ How will Mr Walker laws explain plants which show traces of 3 parents as in plants iα — ? animals as ass & ‹mule› «Zebra & horse» &c of gardens — This will overthrow his system: no because he allows. (p. 301) that one series modifies another ! here is cause of error !

annotationFemale always giving locomotive series .—probably invented to explain the loss of Secondary Character in the male , but is not this more probaly effect of infertility . which likewise affects the female . —

annotation vertically crossed Put th case to Sir. J Sebrght of two half bred mongrels￭exactly￭ like each other being interbre￭d — will o￭ffsprng not be then constant — Ask his Opinnion of Walker's Book.—

annotation cancelled Experiments.— To cross some very artificial male, with old female — according to Mr Walker, the former ought to preponderate in body — accordg to my, Yarrell's thery , «‹old age time as elemnt›» the father. ought , either in first breed or permanently . — ---- Cross half breeds, with some other breeds — to see whether grandfather will appear — ---- Cross two 1/2 breeds exactly similar.t01
